Radiation Hardened Octal D-Type
Flip-Flop, Three-State, Positive Edge
Triggered
Intersilâs Satellite Applications FlowTM (SAF) devices are fully
tested and guaranteed to 100kRAD total dose. These QML
Class T devices are processed to a standard ï¬ow intended
to meet the cost and shorter lead-time needs of large
volume satellite manufacturers, while maintaining a high
level of reliability.
The Intersil HCTS374T is a Radiation Hardened Non-
Inverting Octal D-type, Positive Edge Triggered Flip-Flop
with three-state outputs. The eight ï¬ip-ï¬ops enter data into
their registers on the LOW-to-HIGH transition of the clock
(CP). Data is also transferred to the outputs during this
transition. The output enable (OE) controls the three-state
outputs and is independent of the register operation. When
the output enable is high, the outputs are in the high
impedance state.
Speciï¬cations
Speciï¬cations for Rad Hard QML devices are controlled by
the Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed Electrical Speciï¬cations for the HCTS374T are
contained in SMD 5962-95748. A âhot-linkâ is provided from
our website for downloading.
